Why I Built a Modern Spring Initializr Alternative with Visual JPA & Docker

DEVENDER DALAL — Wed, 30 Sep 2026 16:19:39 +0000

Whenever I start a new Spring Boot project using standard tools like start.spring.io, the workflow usually looks like this:

Select Spring Web, Spring Data JPA, and PostgreSQL.
Download the ZIP.
Open IntelliJ.
Spend the next 2 hours manually creating:
- Entity classes with JPA annotations (@Id, @GeneratedValue, @Column, @OneToMany)
- Repository interfaces extending JpaRepository
- DTO request/response records and MapStruct mappers
- REST Controllers with Jakarta validation
- Flyway or Liquibase database migration scripts
- A docker-compose.yml for PostgreSQL

Standard generators give you an empty Application.java and a raw build file. They give you the foundation, but none of the actual architecture.

That’s why I spent the past few months building SpringForge — an open Spring Initializr Alternative and production-grade Spring Boot Project Generator.

What Makes it Different?

1. Visual JPA Entity Modeling

Instead of hand-writing boilerplate Java entities, you can visually design your entities, attributes, and relationships. It generates clean, audited domain models with @PrePersist timestamps, validation rules, and primary keys.

2. Full Layered Architecture (Not Just Empty Classes)

When you generate a project, you get a clean enterprise layout:

controller/: REST endpoints with OpenAPI annotations and RFC-7807 error responses
service/: Transactional business logic
repository/: Spring Data JPA repositories with custom query methods
dto/: Strongly typed records for API decoupling
config/: Pre-wired beans for Security, Jackson JSR-310, Redis, and Kafka

3. Automated Database Migrations & Docker Compose

Every project automatically includes idempotent Flyway migration scripts matching your entity schema, along with a ready-to-run docker-compose.yml pre-wired with healthy container checks.

Pre-Built Architecture Blueprints

In addition to custom project generation, we built 20 production architecture starters:

🏗️ Spring Boot Microservices Template (Eureka discovery, Spring Cloud Gateway, OpenTelemetry)
📨 Spring Boot Kafka Template (Event streaming with outbox pattern and KRaft Docker)
⚡ Spring Boot Redis Template (Lettuce caching and distributed stores)
🔐 Secured JWT API Blueprint (Stateless Spring Security 6 auth)

Try It Out

The tool is live, free, and produces compile-ready Maven and Gradle ZIP archives for Java 21 and Spring Boot 3.4:

I'd love to hear your feedback from fellow Java and Spring Boot developers! What's the biggest pain point in your current backend setup workflow?
